Answer:
1.97
Step-by-step explanation:
This Is One Answer, There Are More Then One Answer.
100 / 5 = 20 + 27 = 47 / 2 = 23.5
100 = my number
5 = divide by
100 / 5 = 20
27 = add
20 = results of last answer
Then 20 + 27 = 47
47 = results of last answer
2 = half of
Then 47 / 2 = 23.5
<span>width = x
</span><span>length = x+5
2x + 2(x+5) = 46
2x + 2x + 10 = 46
4x = 46 - 10
4x = 36
x = 36/4 </span><span>
x = 9 in </span> ← width
length = x+5 = 9 + 5 = 14 in

Answer:
15.86 inches
Step-by-step explanation:
Area of rectangle = length times width
l = ∛81 inches
w = 3 2/3 inches
= l x w
= ∛81 x 3 2/3
= 15.86 inches
Answer:
3(4x - 1)(2x + 3)
Step-by-step explanation:
Rearrange the equation into standard form
Subtract 9 - 30x from both sides
24x² + 30x - 9 = 0 ← in standard form
Take out 3 as a common factor
3(8x² + 10x - 3) = 0 ← factor the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x term
product = 8 × - 3 = - 24, sum = 10
The factors are - 2 and + 12
Use these factors to replace the x- term, that is
8x² - 2x + 12x - 3 ( factor the first/second and third/fourth terms )
2x(4x - 1) + 3(4x - 1) ← take out the common factor (4x - 1)
(4x - 1)(2x + 3)
24x² + 30x - 9 = 3(4x - 1)(2x + 3) ← in factored form
